there is a difference between "the linux kernel out of the box"
and "a redhat kernel"
a linux kernel "out of the box" will support nothing, since you
have to compile it. it's source :-)
a redhat kernel may well have issues because it is a binary
which could have been compiled with a certain configuration
in mind. i.e the i686 smp kernel is compiled with different
options to the i686 enterprise kernel.
i am not stating this for a fact since i don't have any > quad
machines to independantly verify this, but dell do, so i guess
that's what they're trying to tell you.

it'd not any kind of voltage issue on that pci card/slot is it ?
